Detailed Description

This struct resembles a blocked csr matrix, like Dune::BCRSMatrix.

The data is stored in contiguous memory, such that they can be copied to a device in one transfer.

Constructor & Destructor Documentation

◆ BlockedMatrix() [1/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( int  Nb_,
int  nnzbs_,
unsigned int  block_size_ 
)
inline

Allocate BlockedMatrix and data arrays with given sizes.

Parameters
[in]Nbnumber of blockrows
[in]nnzbsnumber of nonzero blocks
[in]block_sizethe number of rows and columns for each block

◆ BlockedMatrix() [2/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( const BlockedMatrix &  M)
inline

Allocate BlockedMatrix, but copy sparsity pattern instead of allocating new memory.

Parameters
[in]Mmatrix to be copied

◆ BlockedMatrix() [3/3]

Opm::Accelerator::BlockedMatrix::BlockedMatrix ( int  Nb_,
int  nnzbs_,
unsigned int  block_size_,
double *  nnzValues_,
int *  colIndices_,
int *  rowPointers_ 
)
inline

Allocate BlockedMatrix, but let data arrays point to existing arrays.

Parameters
[in]Nbnumber of blockrows
[in]nnzbsnumber of nonzero blocks
[in]block_sizethe number of rows and columns for each block
[in]nnzValuesarray of nonzero values, contains nnzb*block_size*block_size scalars
[in]colIndicesarray of column indices, contains nnzb entries
[in]rowPointersarray of row pointers, contains Nb+1 entries
